Substitute Part Grouping Explanation

Substitution logic for the HM2P07PDE121L9LLF is determined by the following critical parameters:

Position Configuration & Pitch: The main part features 154 total positions (110 signal + 44 ground) at 2.00mm pitch with 5 + 2 row configuration. Substitute parts must maintain identical pitch and row structure to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.

Connector Type & Termination: All substitutes must be header-style male pin connectors with press-fit termination to match the original mounting method and board integration approach.

Electrical Ratings: Current rating (1.5 A minimum) and voltage rating (500Vrms minimum) establish the electrical performance envelope. Substitutes meeting or exceeding these ratings are functionally equivalent.

Environmental Compliance: RoHS compliance and operating temperature range (-55°C ~ 125°C) are mandatory for equivalent substitution in regulated applications.

Substitute parts are grouped into two categories:

Category A - Full Position Match (154 positions): PCN21B-110PB-2PF-G from Hirose Electric maintains the complete 154-position configuration with identical pitch and row arrangement. This part is functionally equivalent despite obsolete product status.

Category B - Signal Position Match (110 positions): Parts 17011102204, 17011102402 (HARTING har-bus® HM series), 5100143-1, and 5106164-1 (TE Connectivity Z-PACK series) provide 110-position headers at 2.00mm pitch with 5 rows. These parts are suitable for applications where the 44 dedicated ground positions of the original design can be accommodated through alternative grounding schemes or where the application requires only signal position density.

Engineering Selection Recommendations

For Full Position Equivalence (154 positions): PCN21B-110PB-2PF-G from Hirose Electric is the only substitute maintaining the complete 154-position configuration. This part is suitable for direct replacement in designs where the 44 dedicated ground positions are functionally required. However, this part carries obsolete product status, which may impact long-term availability and future support. Selection of this part should be limited to applications where the 154-position configuration is non-negotiable.

For Active Production Alternatives (110 positions): TE Connectivity parts 5100143-1 and 5106164-1 from the Z-PACK series are recommended for new designs or redesigns. Both parts are active products with superior inventory availability (3040 and 1516 units respectively), maintain the required 1.5 A current rating and 500Vrms voltage rating, and carry ROHS3 compliance. Part 5106164-1 includes an alignment strip feature in addition to the board guide, providing enhanced mechanical stability. These parts are suitable for applications where 110 signal positions satisfy the design requirement.

For Alternative Sourcing (110 positions): HARTING har-bus® HM series parts 17011102204 and 17011102402 provide active product status with good inventory levels (1042 and 885 units). These parts meet the 2.00mm pitch and 5-row configuration but carry a reduced current rating of 1 A. Selection of HARTING parts is appropriate only for applications where the 1 A current rating is sufficient and where voltage rating specifications are not critical.

Compliance Considerations: All substitute parts maintain RoHS compliance and the required -55°C ~ 125°C operating temperature range. TE Connectivity parts provide REACH Unaffected or Vendor Undefined status, while HARTING parts provide REACH Unaffected status. The original HM2P07PDE121L9LLF and PCN21B-110PB-2PF-G carry RoHS Compliant status, while all other substitutes carry ROHS3 Compliant status, representing enhanced environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can I use a 110-position substitute in place of the 154-position original part?

A: Substitution depends on your application design. The original part includes 44 dedicated ground positions in addition to 110 signal positions. If your PCB layout and connector mating design accommodate a 110-position header, substitutes from TE Connectivity (5100143-1, 5106164-1) or HARTING (17011102204, 17011102402) are mechanically and electrically compatible at the 2.00mm pitch. If your design specifically requires the 44 ground positions, only PCN21B-110PB-2PF-G maintains full compatibility.

Q: What is the difference between the TE Connectivity Z-PACK parts 5100143-1 and 5106164-1?

A: Both parts are electrically and mechanically equivalent 110-position headers at 2.00mm pitch with identical current (1.5 A) and voltage (500Vrms) ratings. The primary difference is that 5106164-1 includes an alignment strip feature in addition to the board guide, providing enhanced mechanical alignment during assembly. Part 5106164-1 also carries REACH Unaffected status compared to 5100143-1's Vendor Undefined status. Selection between these parts depends on whether the alignment strip feature is required for your assembly process.

Q: Why do the HARTING parts have a lower current rating (1 A vs. 1.5 A)?

A: The HARTING har-bus® HM series parts 17011102204 and 17011102402 are rated for 1 A continuous current, compared to the 1.5 A rating of the original part and TE Connectivity alternatives. This difference reflects different design and manufacturing specifications between manufacturers. HARTING parts are suitable only for applications where the 1 A current rating meets the design requirement.

Q: Is PCN21B-110PB-2PF-G a suitable long-term substitute?

A: PCN21B-110PB-2PF-G maintains the complete 154-position configuration and is electrically compatible. However, this part carries obsolete product status, indicating it is no longer in active production. While 1117 units are currently in stock, future availability cannot be assured. This part is suitable for short-term sourcing or applications with limited production volume, but should not be selected for new designs requiring long-term supply continuity.

Q: What are the packaging differences among substitute parts?

A: The original HM2P07PDE121L9LLF is supplied in Tray packaging. Substitute parts are supplied in alternative packaging: PCN21B-110PB-2PF-G in Bulk, HARTING parts (17011102204, 17011102402) in Tube, and TE Connectivity parts (5100143-1, 5106164-1) in Tube. Packaging differences do not affect electrical or mechanical compatibility but may impact handling, storage, and inventory management procedures.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original part carries RoHS Compliant status. PCN21B-110PB-2PF-G also carries RoHS Compliant status. All other substitute parts (HARTING and TE Connectivity) carry ROHS3 Compliant status, which represents enhanced environmental compliance with updated RoHS directives. All parts meet the required environmental standards for regulated applications.
